If speed is normal on other browsers and devices but is slow in Chrome on your primary device, it's a Chrome-specific issue. The download speed of Chrome will return to normal as soon as the connection speeds up. If that's the case, you'll need to speed up your internet connection on Windows or macOS. The problem is device-specific if the download speed is slow on other browsers too. The best way to confirm that is to download the same file on another browser installed on your device and see how much download speed you get. If the download speed is normal on other laptops but slow or unstable on your device, check if the problem is limited to Chrome or is consistent throughout your device. If your internet is also slow on your other devices, take the necessary steps to speed up your Wi-Fi router. Test that by downloading the same files on another system connected to the same internet connection, ideally using Chrome. You must first verify that a slow internet connection isn't the cause of the slow download speed.
